What you need to know on Wall Street today

Welcome to Finance Insider, Business Insider's summary of the top stories of the past 24 hours.

Merck CEO Kenneth Frazier resigned from President Donald Trump's manufacturing council.

"America's leaders must honor our fundamental values by clearly rejecting expressions of hatred, bigotry, and group supremacy, which run counter to the American ideal that all people are created equal," Frazier said in a statement on Monday.

Frazier is one of the few black CEOs of a major US corporation and was the only black member of the council. The resignation came after a weekend of violence at a white-nationalist and neo-Nazi protest in Charlottesville, Virginia. The president did not explicitly condemn white supremacists on Sunday, though he offered a stronger condemnation on Monday.

Trump fired back at Frazier, turning the conversation toward drug pricing.

"Now that Ken Frazier of Merck Pharma has resigned from President's Manufacturing Council,he will have more time to LOWER RIPOFF DRUG PRICES!" Trump tweeted. Here's what the company's track record on drug prices actually looks like.
